SB-RFID-HAT

This is a Raspberry Pi RFID HAT Module operating in the 125Khz frequency range. It supports two communication interfacs: UART for RFID and I2C for Oled Display.

Features

• Standard Raspberry Pi 40PIN GPIO extension header, supports Raspberry Pi series boards
• Two interface options: UART for RFID, I2C for Oled Display
• User configurable buzzer (connected on GPIO 17 of Raspberry pi)

You can also use these 2 projects available in this repository with this hat:

• Attendance_system : A GUI based attendance system using our rfid hat and rfid tags/cards.
• Lock_Pi : You can use this project to log-ff raspberry pi using this rfid hat. To login you have to manually type password to log on again.

How To configure ?

Enable i2c and Serial interface

I2C/Serial interface is disabled by default in Raspberry Pi, To enable it type below command.

sudo raspi-config

• Now select Interfacing options.
• Now we need to select I2C option.
• Now select Yes and press enter and then ok.

To enable serial,

• select interfacing options.
• Now we need to select serial.
• select no to disable serial over login shell.
• Now select yes to enable serial hardware port then ok.

After this step reboot raspberry by typing below command:

sudo reboot

Install Required Libraries

• sudo apt-get install python-smbus
• sudo apt-get install i2c-tools

To verify the list of connected device on I2C interface, you can run below commond :

sudo i2cdetect -y 1

How to run SB-PI-HAT examples

To run examples of SB-PI-HAT, clone this repository by executing below command

git clone https://github.com/sbcshop/SB-RFID-HAT.git

cd SB-RFID-HAT

python3 rfid.py (Without Oled display, output on terminal/shell)

OR

python3 rfid_with_oled.py ( To show detected tag id on Oled as well as on terminal/shell)

sb-rfid-hat's Issues

Relay GPO

Hi, where can i connect a door unlock relay?

Thank you

Reads seeming to happen when I start to remove the RFID Tag / Also getting random 000000000000 Reads

I had a fully working setup that I shipped off and we were good to go.

I attempted to replicate and am suddenly getting random reads without any RFID near the device of 000000000000

Also , When I use a tag / it appears that it doesn't read the tag and finish until I remove the tag from the reader. (This is using your examples.

Doesn't work at all on Pi4

Bought two boards just getting random info and or 00000000000 from both of them. Just NOT working. I doubt its hardware would be unusual to affect both boards. I've tried with multiple pi boards too as I have a bout 10 of them. Using Debian, latest 32-bit OS from Raspberry Imager. Python3. All set 9600 baud. Reahce out for support from sb-components but nothing back yet. :(
